Question

Giải bpt : \(5x-\frac{3-2x}{2}>\frac{7x-5}{2}+x\)

 

Answer 1

\(5x-\frac{3-2x}{2}>\frac{7x-5}{2}+x\)

\(\Leftrightarrow\) \(\frac{10x}{2}-\frac{3-2x}{2}>\frac{7x-5}{2}+\frac{2x}{2}\)

\(\Rightarrow\) \(10x-3+2x>7x-5+2x\)

\(\Leftrightarrow\) \(10x+2x-7x-2x>-5+3\)

\(\Leftrightarrow\) \(3x>-2\) 

\(\Leftrightarrow\) \(x>-\frac{2}{3}\)

Vậy ................

Answer 2

4x > (5x -2)/2

4x - 5x/2 > -1

3x/2 > -1

3x > -2

x>-2/3
